Pals show healthy concern for Renee

Renee Zellweger looked to be in good spirits Tuesday at 'Chicago's' L.A. premiere, but friends are worried about her health.

Renee Zellweger is looking so frail these days, friends are said to be seriously worried about her health.
At the premiere party for her film "Chicago" at London's Cafe Royal last weekend, a source told us, "Her friend Elton John was practically trying to put an hors d'oeuvre in her mouth. He raised it to her lips and said, 'Come on, have something.' Elton and David Furnish were trying to cheer her up." But the actress still refused to eat, the source added.

London's Daily Mail reports that the star, who plays Roxie Hart in the film version of Bob Fosse's Broadway musical, "was staggering around the VIP lounge with David's phone and having a very animated conversation interspersed with hysterical giggling."

Things seemed to get worse later when, our source says, "She ran into the bathroom." According to London's Express, "Renee's people [were] gathered outside discussing whether or not to call an ambulance. It sounded serious." And a friend of the actress was overheard by The Express saying, "She hasn't eaten all day. She was being sick. We've got to get her home." About 30 minutes later, she was escorted from the party.

The actress, who looks so thin in "Chicago" she makes Catherine Zeta-Jones appear fleshy, looked slim but healthy at the movie's premiere in Beverly Hills on Tuesday night.

A rep for the Buena Vista film company said: "Renee wasn't sick [in London] as far as I am aware. If she was looking distressed, it would have been because she was absolutely exhausted."
